Hi welcome to Te Down! Tuesday Yes, I'm excited it's another oscilloscope. It's a new Ry Gold DS 2000 series and we haven't torn down a Ryol oscilloscope since the DS 1052 and that was years ago. Pretty excited to see what's inside this one. See if the build quality is any good? see if they've improved since the Ds1052e.

So you know what we say here on the Eev blog: Don't turn it on. Take it apart. And for those of you who haven't seen the two Scopes side by side, the new 2000 Series has a much bigger screen. It's absolutely huge and of course it's bigger wider.

It's about the same depth, but it's a a fair bit heavier. So there's going to be lots of metal and shielding and stuff inside this puppy compared to the older Uh 1000 series scope. So let's crack it open and I Do expect this thing to be pretty easy to take apart. There's no power button on the top, which when I took my original uh Ryol 1000 series apart I actually broke off the knob.

So we've got a uh, a few screws down the bottom here. that's about I Think well, that's probably it under there. There we go, couple under the handle and they should pop right out. They're a little bit tricky those top ones Tada and exactly what expected.

full metal shielding. Check it out. it's got the fan on the side and uh, to get this off, it looks like we're probably going to have to take off this BNC nut here. and uh, a few screws on the top and the side there, but that should just lift off easily and check out even the shielding they've put around the uh I Main's input connector there.

I Like that? That's terrific. That is well done. They've uh, got of course metal threaded inserts down in the case here, but let's take the rest of it apart and check out these two pin headers penetrating the metal shield. here.

it's got hack written all over them. if I look at the silk screen through there that says SPI boot oh that could be a hacker's Delight that one and this one here is, uh, look at the silk screen, it's got ground VCC reset and uh, what is BR GD whatever that means go figure. But yeah. interesting and here we go.

I think I got most of the screws out. let's hey hello yeah, looks like it just LS out. The fan is probably going to be attached over here, but that shouldn't be a a drama. Ah, fan and P and well, power here we go.

Taada, we're in. Oh beautiful look. It's all laid out for us. Wonderful! This is really looking quite nice.

I'll just disconnect the main power rather tight. There we go. the fan bang and that's it. A that's just beautiful I Love it when products are so easy to take apart like that.

Wonderful And first glance, this board just looks beautifully laid out. and uh, there's the input shielding can there? couple of main, uh, heat sunk devices. We'll go into detail of all the parts, but it's just beautiful and accessible. I Love that and it looks like this board is going to pop out pretty easy too with these main screws here with these gold uh pads on them and uh, if we just undo that flat Flex cable there I think the rest of the board should just lift out.

probably have to do, maybe undo the buttons on the front, uh, the knobs on the front or something like that. but that's the main board. And here is the rest of the shazzy. and check it out.

They've got another beautifully shielded power supply here. They've uh I don't see any uh RFI uh bead on there at all and it's probably not easy to see down in the ISC connector down in there. but uh, they're nice properly heat shrunk Mains rated cabling coming down. Beautiful little Earth bonding point there with two separate wires, one coming directly from the I connector, the other one going off into the power supply.

They're heat shrunk, they're properly crimped. There's a shake proof washer on there. by the looks of it, it's all really tight. beautiful, well designed.

and look at that. They haven't skimped at the cable retention mechanism either. Beautiful. That's a double-sided uh, adhesive tape one stuck down.

It's all neat and tidy. It's just the correct length for the cable harness, just to just as long as it needs to be to get access to it and assemble. and uh, service it by pulling it back apart as well. I Probably not designed by Ryol? Um, probably.

uh, subcontracted out to a power supply specialist company. Most companies do that so I'd expect to see a quality and safe, well-designed power supply. probably not using Prime Speec, you know, Panasonic Caps or or something like that. but I certainly wouldn't expect one.

hung lows? Well I may have been a little bit wrong on the uh third party thing cuz that's clearly got Ryol on it. and I can't see any other third party markings on this power supply board. but uh wow. This is really good folks.

This is very welld designed. Check out out the celastic everywhere. For starters, they've celastic everything down. They're doing everything right.

Let's have a look here. They've heat shrunk their inductors, their chokes on the input. Here they've heat shrunk those are using proper Mains rated caps of course, as you'd expect, um, the uh inductors and Transformers look first class quality. Hard to tell, but ah, you know it's just the vibe of it Australians will know what I mean and uh, the capacitors here output all the output capacitors.

They're um, Epcos brand. There we go. They're not bad, they're not uh, caps on or anything. uh horribly bad.

Like that they're all 105 C rated Epcos I Like it. Lots of uh chokes on the output as well. So they're really doing really doing the business there. Not sure what those output devices are.

not that fuss really, but uh, they're You know, they're all nicely. uh, insulated. They're doing all the right stuff. I See Shake proof washers on there I Believe and uh, that folks.

Looks like a very nice power supply. You can see the split I Haven't taken the board out yet, but you can see the isolation. the high voltage isolation slot underneath those opto couplers there feeding back uh to the primary from the isolated secondary side, so they're certainly doing the right stuff. There doesn't seem to be a matching slot under there, although they could be.

I' have to take the board out to see that. but uh, they certainly spared no expense on the Silicon stuff, just blobbing all this stuff down. There's your input Bridge rectifier. By the looks of it, that's not.

uh, heat sunk at all. Doesn't really need to be. but check this out. I Like this bit of attention to detail, look at that diode there.

It's got little ferite bead on the cathode there of that Dioo figure. they've determined well. we need to slightly take the edge off that thing. so slightly take the edge off the waveform there.

so we're going to whack in a uh, an RF bead onto that thing. Brilliant! I Love it. Huge thumbs up more uh, isolation slots down here. there we go to separate the Earth from the uh, um, active and neutral side of it.

More slots down in there and up the top there. Oh, there we go. I Don't think I can find a single thing wrong with that power supply folks. I'd Expect that one to last quite some time I assume that the main 450 volt um, rectified.

DC uh Cap: there is also on Epcos. it looks, uh, very similar. So I'd expect that one to last at, you know, a reasonable length of time. They've certainly done all the right Engineering in that small attention to detail stuff they've cable tied down that main cap.

they've gone well. The Silicon is not good enough. We're going to do both really belt and braces kind of engineering. I Really love it.

and uh, we've got our input surge protection of course, input filtering stuff, so it's certainly designed uh to meet all of the uh International requirements for such switching power supplies. I'm sure that have no problem at all getting that type approved in any country. Now we'll take a look at the main board in more detail here. Um, but beautifully laid out, nice and modular input can over here your input triggering uh, circuitry.

Over here some power supply stuff up here. uh, a Ryol branded chip which we'll take a look at here and we've got uh clip retained heat sinks here. but uh I'll just mention somebody on the Forum their uh Ds2000 series scope. Actually, these, um, retaining Clips weren't solded on and they actually popped off and his scope failed.

It probably shorted out something else and it went ping and uh, apparently, so something to watch out for. It'll be interesting to see once we get this board out if mine is solded correctly, but the soldering looks first class on this, by the way. Anyway, we've got uh processing up the top here. black fin processor.

We'll take a look at more memory stuff. Um, we've got all the power supply nicely modular. Just in the individual little modules, you can see the individual uh, ground planes surrounding those. Beautiful.

Now the only flux residue I can find on the board is around this, uh, presumably hand soldered uh front panel B andc connector. Here you can see some of the residue left on there. Not a huge deal really. Um, this, uh, looks like um, these the soldering points over here.

That would be for the uh front panel uh test Point um test signal. But apart from that, the soldering really is. uh, first class on this thing and I cannot fult it at all. And this is the external input trigger circuitry.

It's got it even written down on the board. There external input: There's an input Uh series resistor. there goes into a few large 1206 passives. there couple of so a bunch of So 23 devices around there that's a Texas instrument branded chip probably some sort of uh opamp or something I'm not sure and another device down there.

little look little MLF package not sure what's happening there. Another TI part got quite a few TI Parts there p274, 22k av31 don't know it offhand. uh there a voltage reference test point, a couple of more devices around there, it's all pretty bug standard stuff and a 4051. Got to have a 4051 and check out the V stitching all the way around this external put circuitry.

they've gone. Oh man. I Don't want anything to get in or out of this sucker. Let's just Stitch the hell out of it.

Here's a couple of switching power supplies up in the top corner here. Beautifully laid out. Look at the heavy via stitching on this stuff. Beautiful, nice, tight, compact layout.

They've got them, um, uh, separately isolated in terms of the grounds. I'm not sure what voltages they are. they're probably, you know, core voltages for, uh, some of the main chips like 1.2 volt core or something like that. Perhaps we've got a TDK buzzer on there.

Spared no expense. There's a 25 MHz uh oscillator there. It's not the main one. There's a couple of them on this board.

so uh, that one's PA on a chip. But look at this. Look at this puppy here. There's something on top of that chip.

There's something on top of that. It's really rather weird. So that oscillator is clearly going into this little puppy here. and and maybe that's sort of some sort of uh, clock driver or something like that.

For the main Ryo device up here, which is a u0141 who knows what that is, it could be a custom Asic device. It could be just a uh, you know, a rebadged off-the-shelf thing Else we don't really know, but clearly they've tried to disguise this chip down here to for uh for this main Ry gold chip which is driving, presumably the clock in that thing I Can only presume by the location of this uh oscillator here next to this and then the Ryo chip all the way over here. Can only presume that goes into here and that goes off to the main riol. Asic And check it out.

It's almost as if like it's a bit of tape or something. You can see the laser markings on the chip underneath there now. I'm going to try and scrape this off. It's only a tiny little tiny little thing, so it looks like it's on top.

It's really, it's rather, no, that's it's. sort of almost like it's You know, it's sort of baked on there or something weird. Ive I've never seen anything like that before. Seems to be some sort of new method to sort of cover up the identity of what that chip is.

go F bigger and they've got so 22317, uh, low Dropout voltage Regulators uh there quite a few of them scattered around this board and as you can see, they got a tiny little heyink attached to them. Really nice little layout. nice VI stitching. and if we have a look at the main Ryo device here, whatever it is, we can uh, see all of the differential pair Serpentine traces leading up to this main BGA device up here with the heat syn on it and you can see how they're uh, not only adding the serpentine Parts into each pair to match.

say this pair here with the one next to it and match the length of the pair, but they're also adding the little single sided wiggle in there to tweak and match. Um, the individual um pair. It's each line in the individual pair so that Trace there with the Wiggle in It Is Designed so that it exactly matches the length of its companion differential Trace next to it. Classic.

Um, you know, uh, highspeed signal Integrity Layout: They've done it perfectly and of course this board would be multi-layer probably. uh, six or something like that. They might have even got away with a a four layer on here and that would be controlled impedance and we' found ourselves the main sampling SD Ram It is uh, 512 megabit HX H5p, S 5162 GFA Ddr2 SRAM and that's C SD ram and that's coupled into this main heat sunk device here and there's a companion one over there as well. and they've also got another one here tied into adjust the one by the way, not too tied into this secondary device over here now.

I Think we can figure out what this ryol chip here is by deduction. Let's lift off the front end here and uh, we'll find that there's probably no Adcs under here. So Aha and to get this can off, we're just going to have to bend up some little tabs we've got here and that should allow us to Tada pop the lid on it. There you go.

Now we'll take a look at the front end later because it looks very similar to the Ds1052e but as you can see, there's no ADC in there. This is just a uh differential driver. So where are the Adcs you ask? The data has to come out of the front end here and it's got to go via differential pair which will be on the inner layers in there. That's why you can't see any traces going from the input.

Uh RF front end can over to here, here or anywhere else because there's no surrounding. These aren't the Adcs here, right? Not sure what they are, but they're clearly not the ADC. So clearly this custom device is the ADC Now whether or not it's an off-the-shelf one and they've just rebadged it. Uh, Ryo At the you can do that with the manufacturer, you can get them to.

You know if you order enough, say I don't want your part number on it I want my part number on it. but that has got to be for all money. at least. the analog both analog to digital converters, multiple analog to digital converters or something like that controlled via this.

um, this oscillator here will be like the master clock for it and all that sort of stuff. And here are the outputs: All these differential pairs going from presumably ADC up to the main Uh FP Presumably this is an Fpga under here, which contains all the sampling, you know, logic, and all that sort of stuff. and it's got the two sample memory buffers next to it Bingo That's it. And then you've got the output from this flowing down over here into another Fpga or PL which will have a look at uh with some more memory next to it um, and then eventually flows over into the main Um processor DSP processor over here.

So that's clearly what is happening there. and then if you're curious to know what this bunch of surgery is here next to it, that's like a probably another Fpga under there. we've got some memory next to it. another uh, Ddr2, SD Ram, but that's clearly the display processor.

Look, it's just got a couple of lines going, maybe just a Serial bus or something going from one side. you know, going from the main acquisition. Asic Uh, well, Asic Fpga probably over to this display processor here because it's going. It's a dead giveaway.

Of course it's going down to the LCD display flat Flex cable. So clearly that is the role of this device here. And then they've got some traces coming out of it by the looks of it. Once again, coupled into here, this Fpga sort of glues the uh, the data coming from the acquisition engine sort of into the display processor and also takes commands from the DSP Which of course the DSP is not going to be doing a huge amount, it's just going to be doing like the user interface stuff and uh, things like that it's not, you know, busily.

Um, you know, updating the display that's all offloaded to that display processor there. And if you remember the sampling memory here, 512 megabit each. divide that by 8. That's 64 megabytes and there's two of them.

This is a two channel scope so that they'd probably be dedicating one of those per channel, of course. So these, this thing, um, well, in theory has 64 mbes of uh, sample memory per Channel and on the display device here we have two Cyprus uh srams a Cy 73 138c and that's an each one of those is an 18 megabit pipelined SRAM So that's how they're going to get really super fast display updating on this thing. and for what I probably call like the uh, glue fpga here, they haven't gone for one of the big two uh, xyl links or Altera they've gone for an Actel Pro AIC 3 and it's got its own local oscillator there as well. And we've got some spansion uh, flash memory here and also the JTAG header down here.

So this thing, uh, pretty much a hacker's Delight really and then linking these two. we've got uh, some Lvds, uh, bus drivers there. and then we've got an Issi uh, 256 megabit SD ram. that's a is 42s 16160 D which is, uh, clearly the main memory for Tada The Analog Devices black fin processor and that's an Adsp BF 526 I'm not sure if that's the same one used in the right Ds1052e I forget.

but uh, there you go. That's the main processor. This is probably a flat Flex cable going over to the Uh keyboard or the keypad front panel keypad. and there's uh, presumably the USB host interface.

Haven't looked that one up, but that looks like a Cypress USB host and we've got our Ethernet interface as well. all tied into the black fin processor there with its own dedicated um uh, SD ram memory memory. And then we've got the uh, the flash as well. That's all the program Flash And then of course we go over into this glue Fpga or whatever it is and Back Again into our uh display uh processor.

and there's that tantalizing SPI boot header and then this mysterious one over here ground VCC reset and BK GD and this circuitry here is coupled around the front panel USB connector here. So they've got their own local regulator here and these devices. These two Uh chips here would be associated with power you know? uh providing um Power current limited 500 milliamp power to the front panel USB port. And here's the date code: Ds2000 Main Board Version 1.0 19th of March 2012 You'll note that the Real Time Clock Crystal there a little bit bodgy solded down, but at at least it is uh, solder down, held in place, bit of solder residue, flux residue left on there.

but uh yeah, not a big deal. So although I can see the thermal grease under there, I am actually going to try and take this sucker off and uh, see if we can get access to see what that device is under there. My guess is an Fpga of some sort should be able to clear that off and uh, see what we've got under there? This is the display processor and surprise surprise, it's a xylin Spartan 6. Pretty new technology there.

XC 6s Ls25 and that uh, contrast with the Uh actel Fpga we found elsewhere. So what's the bet? that uh, this one up under here is also a Spartan 6. So unless they had drastically different Uh system requirements for these Uh two devices, then they probably would have made sense to consolid at. and you know, uh, into the one part and choose a Spartan 6 under here as well.

but it could be something else we'll see. There you go: I was bang on Spartan 6 as well XC 6s lx25 so hey, they got those at a discount and it's most likely that both of these will be sharing that same JTAG interface up there because uh I can't see another JTAG interface for this one over here. So all up there, we got three JTAG interfaces, one up here for these two Spartan six Fpgas one over here for the actel, FP the smaller actel fpga and one over here for The Analog Devices blackf DSP processor. And here's the front end analog input and it is, uh, quite reminiscent of the Ds1052e although there seems to be a bit less in here I Think or maybe it's just, uh, spread out a bit more now.

Both Channel 1 and Channel 2 look to be absolutely identical, so we're only looking at Channel 2 here. As you can see, we got a couple CP of uh, couple of relays in here H We've got a couple of trimmer caps in here for this. um, switchable attenuator part of it for the higher end voltages. Um, we've probably got our um, uh, this I haven't looked at the part number yet, but that probably will be a programmable gain amplifier driving the ADC That'll be a differential output programmable gain amp.

There'll be a Jfet and a couple of transistors in there to drive that thing. um, high-speed Op amp over here. and that's it's I think its operation is going to be pretty, uh, very similar to the DS 1052. Of course, these Scopes have a um upper bandwidth limit of 200 MHz as opposed to 100 MHz in the DS 1052 e.

So it's basically just more of the same. They've just um upped it to 200 megaherz. They've chosen specific parts and you know, tweaked it to be able to do that. and I'm having a hard time time reading that presumably programmable Gain amp chip there and the one next to it.

So I'm going to have to get out the digital magnifier and woohoo, what do you know? it's I'm not sure if that's easy to read there, but that is Ryol. They've got a custom Ryol branded chip there, but once again, it you know it may not be a custom device I probably doubt it. They probably just maybe to prevent, uh, reverse engineering or something like that. They've just, uh, asked the manufacturer to relabel it and Rebrand it as Ryo for them.

But you know I don't know it could be custom. but I doubt it. And if we have a look through our mantis scope here, there's the culprate Ryol VM 13ab Whatever on earth that is. But yeah, my guess is it's a programmable Gain Amp differential output and I'm not sure if you're going to be able to see that, but the other device inside this, uh, front end has got like that magic tape on it or something that we saw on the other chip on the main board earlier.

So they're They're clearly trying to, uh, you know, stop reverse engineering or hacking of this thing by masking a couple of the chips in there. Bastards. So is it hackable like the Ds1052e to get the increased bandwidth? I don't know, Your guess is as good as mine? Is there a verctor in there like the other one and they just switch it in? uh, digitally controlled under the software to limit that bandwidth in the amplifier? Perhaps it could, uh, very well be in there, but I'll leave that up to somebody else can hack. They probably fix the software thing, so I'd be very surprised if you just do do it easily through software as easier as it was last time Anyway, cuz they've shown that they've uh, fixed those things with the firmware.

um, upgrade, so you know. But it's the easiest way to bandwidth limit these things is in the analog front end they wouldn't be doing in software. I Think there's still got to be a line coming in here with some sort of, um, you know, Hardware filtering of that analog bandwidth. Now, this section here is interesting.

Right next to the Chann one input here, and there's four devices here. There's a regul, presumably a local regulator power in it. There's some other little uh so 23 device down here and another device up here. and if we zoom in on it, then uh I'm not quite sure what that device is.

It's got 21 a 3878 on it. There's a couple of voltage points next to it. One is uh 5 Vols I Presumably that's not 0.5 Vols I Think that's a little plus 5 Vols and a plus 6.3 Vols over here. Jeez, what is it a valve heater or something like that for an old valve? 6.3 volts.

Wasn't it for the Uh heater for the old valves? I could be wrong I'm sure I'll be corrected by one of the old gray beards, but there are four of these like that identical layout. There we go local, um low Dropout Rig triple1 7 again and then we've got another TI device a ha 595 and there it is. Channel One SEC Channel One fur Channel 2 fur Channel 2 SEC and that's pretty much all she wrote on the main board there. I Mean you know there's a a couple of stuff here for the backlight inverter and another um couple of uh core voltage uh, switching voltage Regulators around there for core voltages for various uh, Fpga and things.

but yeah, that's about it I'd say we, uh, let's try and take take this board out. flip it out and uh, see what's on the you know, the underside? There's going to be some bypass caps on there clearly cuz there's no bypass caps anywhere around any of these devices at all. And of course, these uh uh, Fpga uh here. fairly dense.

um Spartan sixes. They need bypassing on the bottom and everything else, so there'll be a bunch of passives on the bottom and that's probably it. But there'll be another board on there for the front panel as well. So here we go.

It's not easy to get this board out. you've got to take out the metal frame first. Take all the knobs off the front of course and these are all uh uh. metal threaded inserts on here here.

beautiful molded. There's the buttons. no problems whatsoever and we'll have to take no doubt the B Andc off here. But here's the front.

Here we go. This is rather interesting and check this out. Look what it says: Secretary Bird Smk2 Secretary Bird I What is that the code name for this thing? curiously I Think it has something to do with that symbol there, which is probably the Secretary Secary. Australians will get that joke.

uh Secretary Bird perhaps? Is it the name of an actual bird or is it I Don't know. and what do you know there is such a thing as the Secretary Bird it's from Africa Go figure. There's not a huge amount on this board, just the rotary encoders. These are all pushable of course.

and uh, we have the nice springloaded Zo Zoom knob here. Rather like that. it's really sexy and there you go. not a huge amount doing on the back here.

The two channels have actually removed the bottom uh, ground plane out of that for uh signal Integrity performance reasons. but uh, apart from that, yeah, we've just got some uh, basic passives and there's some resistor Terminators on there. there's the bottom of the BGA down in there. if you you know if you want to zoom in on that, you can see the classic uh bypass capacitor layout for an Fpga sort of.

you know, done that dozens and dozens of times. that uh star Arrangement Like that that's just the way they, um, uh, generally fit in. In terms of the power pins under the BGA there's some resistor Terminators Nothing terribly exciting. The Main: Pro I Think that's the main.

No, that's the uh, that's the other Fpg up the top there, there're the two memories. uh, you know DDR termination resistors and uh, that is about all she wrote on this board. There's the soft power button down there. of course.

this thing is operational all the time and it gives that heartbeat type uh, lead on the front power button and you can see some residue on there as well. All these hand solder connectors certainly, um, have a bunch of uh residue left. They haven't used a no clean flux on there, but uh, not a huge deal really. What's that device in there? and it's another TI chip? Not sure what that one is or what it's doing, but there you go.

There's the bottom of the uh, uh, that custom Ryol chip on the front end there and it's identical between Channel 1 and Channel 2. And here's the back back of the keypad board. My guess would have been a little micro or something like that, but it's a lattice Mark IO PL and what they've done is completely gunked up this flat Flex cable I Don't know if there's a connector under there or not, whether or not it's maybe solded directly on or something like that. but uh, that runs under the LCD over to the other board over here, which uh, then goes off to the main board down the bottom.

there. And the other thing to note too is there's a cutout in the metal panel here. and there's also a molding in the front panel for some sort of small connector interface. I Don't know a uh, potential digital section I Don't know your guess is as good as mine.

Check out this solded tab going over the top. From the keyboard board here to the main shazzy, they've decided that they've got to ground that for some Emi You know reason and it's time to reassemble. This thing was a pain in the butt getting the Uh buttons through the front panel. By the way, if anyone's looking at taking these apart, getting it back together is not necessarily easy.

Beauty So there you have it. there's new Ryo Ds2000 Series this is the DS 2200 but they're all the same. H Wrong knob. Oops Interestingly, the Uh silk screen on that front panel is all the way under the noob.

There There you go. go figure. and uh, that is a beautifully engineered scope. I Really like it? I mean this is an 800 $7 800 class scope.

Of course for the entry level uh one? I mean the analog bandwidth you're just paying for. you know, software options? Uh, basically. oops, wrong knob? Do there we go. There's our scale knob, which should be bigger.

bit disappointed that the horizontals the same. H That's a trend with all Scopes these days. I long for the day when they have a nice big horizontal. you know you think this would be the horizontal.

It's not, it's the zoom. Oh man, very tectronics likee there. But there you go. that is the new Ryol DS 2000 series scope and that is an absolute winner.

It really is that is beautifully engineered for, you know, the sub $11,000 price category I think it's awesome I Really couldn't fault the Uh Engineering in this thing at all. and I think it'll be a pretty darn reliable scope and probably pretty hackable as well I would suspect and I'm sure there'll be no shortage of people working on that just for fun. You know, play a game or POG on it. go figure.

Anyway, if you want to discuss it, jump on over to the EV blog forum and if you like tear down Tuesday please give it a big thumbs up. Catch you next time y.
